Position Overview

Principal Modeling Simulation and Analysis Engineer or Senior Principal Modeling Simulation & Performance Analysis Systems Engineer – Baltimore, MD. 100% on-site.

Responsibilities
  • Accelerate delivery of capabilities through performance engineering, software integration, and test activities leveraging credible modeling, simulation, experimentation, and analysis.
  • Apply MS&A techniques across all phases of radar systems engineering to assess, validate, and optimize system and subsystem performance, working with IQ data from simulated and real-world collections.
  • Perform performance-focused modeling and simulation on high-performance computing grids, conduct trade studies, and generate systems engineering documents, reports, and operational documentation.
  • Utilize MSE&A frameworks to support software integration, algorithm development, and radar mode validation, ensuring consistency between modeled environments and real-world data.
  • Assess system capabilities by linking requirements to performance metrics and mission threads, defining and verifying interfaces, and supporting integration and test activities.
  • Support systems engineering radar algorithm validation by tracing IQ data through the radar processing chain, comparing modeled and collected data, and identifying performance shortfalls and corrective actions.
  • Plan, generate, and execute verification and validation artifacts supporting system design verification testing and system acceptance testing, including test plans, procedures, and data review packages.
  • Develop and improve performance models, simulation frameworks, and analysis tools, including physics-based radar models, threat and environment models, and command-and-control interactions.
  • Perform large-scale data analytics, probabilities, and statistics, including design of experiments techniques.
  • Collaborate with interdisciplinary teams to diagnose performance issues, recommend design changes or tuning, and ensure integrated solutions meet requirements.
  • Generate and present technical material for internal and external customer briefings, technical reviews, and design/test readiness events.
  • Innovate to solve problems and identify improvements across MSE&A products, performance analysis workflows, and integration/test approaches.
  • Develop, integrate, and use advanced graphical user interfaces and visualization tools to explore, validate, and communicate performance results.
